Great service as always and a great product.
I bought this with the idea that i'll be able to drop additional hat usage under the helmet, and indeed, with the hoodie that this first layer has you don't need to carry the extra hat/ beanie that you would put under the helmer in colder days. It keeps warm as a first layer, however on colder days i've added an additional first layer, along with a fleece and a jacket, for max comfort when going just downhill. For skinning/ going uphill days, for sure you will not need anything more than this piece.
One of my favourite tops. Comfortable to wear and warm.
